Simple and fun, but emphasis on simple

This is a fun little step sequencer that has you creating music in seconds flat. My only complaint is it might be a little too simple. There are very few presets, a rather small grid and no option to import your own sounds. Without those features this is little more than a toy. That said, I assume it was the intent of the appmaker to create something basic and fun. If that is the case, this is a success.

Limited

Very limited app - I guess it's ok for free, and there are no banner ads, which is nice, but it does not sound good. There are better free apps out here, so keep looking.
